50 to 85 percent.
In modern times - up to 1975 at least - 70% of the Earth's Oxygen {O2} is produced exclusively by phytoplankton.
The oxygen is produced by phytoplankton in the top layers of the Ocean, especially by desmids, diatoms and dinoflagellates---tiny single Celled organisms with shells made of 'glass'.

The ocean produces about 50-85% of the Earth's oxygen through phytoplankton and seaweed. While the Amazon rainforest is often praised for its oxygen production, it actually contributes a smaller amount compared to the ocean.

How is oxygen processed for us?
Oxygen is inhaled through the respiratory system, where it enters the lungs and diffuses into the bloodstream. It is then transported by red blood cells to various tissues and organs in the body for cellular respiration. During cellular respiration, oxygen is used by cells to produce energy in the form of adenosine triphosphate (ATP) through the process of oxidation.
